This change refactors the Looppoint files. While functionally equivalent, this classes have been moved and altered to be easier to handle going forward. The following changes have been made: - New classes have been added to represent the data structure of the Looppoint JSON. This simplifies the parsing of JSON files and makes it handle Looppoint data structures. Ultimately this is hidden from the user via the new 'gem5.resources.Looppoint' class which will be the front-facing class for Looppoint interactions. - The `LooppointCheckpoint` class has been replaced with `LooppointCsvLoader`. This new class takes in a CSV pintpoints file to load necessary looppoint data. - The `LoopPointRestore` class has been replaced by `LooppointJsonLoader`. - All Looppoint classes have been moved to `gem5.resources`. This will make it easier when we add Looppoints as specific gem5 resources.

This is the gem5 simulator. The main website can be found at http://www.gem5.org A good starting point is http://www.gem5.org/about, and for more information about building the simulator and getting started please see http://www.gem5.org/documentation and http://www.gem5.org/documentation/learning_gem5/introduction. To build gem5, you will need the following software: g++ or clang, Python (gem5 links in the Python interpreter), SCons, zlib, m4, and lastly protobuf if you want trace capture and playback support. Please see http://www.gem5.org/documentation/general_docs/building for more details concerning the minimum versions of these tools. Once you have all dependencies resolved, type 'scons build/<CONFIG>/gem5.opt' where CONFIG is one of the options in build_opts like ARM, NULL, MIPS, POWER, SPARC, X86, Garnet_standalone, etc. This will build an optimized version of the gem5 binary (gem5.opt) with the the specified configuration. See http://www.gem5.org/documentation/general_docs/building for more details and options. The main source tree includes these subdirectories: - build_opts: pre-made default configurations for gem5 - build_tools: tools used internally by gem5's build process. - configs: example simulation configuration scripts - ext: less-common external packages needed to build gem5 - include: include files for use in other programs - site_scons: modular components of the build system - src: source code of the gem5 simulator - system: source for some optional system software for simulated systems - tests: regression tests - util: useful utility programs and files To run full-system simulations, you may need compiled system firmware, kernel binaries and one or more disk images, depending on gem5's configuration and what type of workload you're trying to run. Many of those resources can be downloaded from http://resources.gem5.org, and/or from the git repository here: https://gem5.googlesource.com/public/gem5-resources/ If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
